Answer:

a) x4 b) Eyepiece x10 Objective x40

Step-by-step explanation:

a) x4 magnification

The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.

b)

Eyepiece Lens: the lens at the top of the microscope that you look through. The eyepiece is usually 5x, 10x or 15x power.

Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers.

To get 400 we need to use a combination that, multiplied together, will give us 400.

If the eyepiece lens is 10x then 400/10 = 40

So if we use the 10x Eyepiece lens with the 40x Objective Lens we will get a total magnification of x400.
